Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference in downlink and uplink wireless communications due to transmissions from neighbor base stations and other wireless RF transmitters degrades network performance, especially with increasing mobile broadband demand and deployment of short-range systems.
Innovation Solution
A method for cooperative UE operations involving determining processing capabilities and reporting to a serving base station, receiving a configuration message, and conducting cooperative communications using identified modes, as well as a base station determining and transmitting a cooperative mode configuration based on UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooperative UE operations are implemented to mitigate interference, then network performance is improved, but device complexity increases due to multiple operational modes and capability reporting requirements
Solution Approach 1:
The patent implements dynamic selection of cooperative operational modes based on real-time processing capabilities and channel conditions. The UE determines its processing capability for each cooperative operational mode and reports this to the base station, which then configures the appropriate mode. This dynamic adaptation allows the system to optimize network performance while managing device complexity through conditional activation of cooperative features rather than permanent complex hardware.
Solution Approach 2:
The patent changes the operational parameters of the UE by introducing configurable cooperative operational modes with different processing capability requirements. The base station configures specific modes based on reported capabilities, effectively parameterizing the complexity level of cooperative operations. This allows the system to adjust the degree of cooperation and associated complexity based on network conditions and device capabilities.
2Adaptability or versatility
If multiple cooperative operational modes are supported, then adaptability is improved, but processing capability requirements increase
Solution Approach 1:
The patent implements partial cooperation by allowing UEs to selectively enable only those cooperative operational modes for which they have sufficient processing capability. Rather than requiring full cooperative functionality, the system allows UEs to participate in cooperative operations at a level matching their capabilities, thereby achieving adaptability without overwhelming processing requirements.
Solution Approach 2:
The patent segments the cooperative operational modes into distinct categories with different processing capability requirements. The base station receives capability reports for each mode separately and configures appropriate modes individually. This segmentation allows the system to offer multiple operational modes (improving adaptability) while ensuring each mode has manageable processing requirements.

AI summary
Providing downlink and uplink processing is disclosed for a cooperative user equipment (UE) operations. A UE participating in the cooperative UE may determine a processing capability associated with each cooperative operational mode of one or more cooperative operation modes of which the UE is capable. The UE sends a cooperative capability report to a serving base station that includes identification of the one or more capable cooperative operation modes and the processing capability of the UE associated with the each cooperative operation mode. The base station may then configure the UEs based on this capability information. The UEs would receive a cooperative mode configuration message from the serving base station with the configuration of a cooperative operation mode for the UE. The UE may then conduct cooperative UE communications using the configured mode according to its associated processing capability. Other aspects and features are also claimed and described.
